COUPLINGr-HOSE Specification of Letters Patent.

Patented April 20, 1909.

Application filed October 27, 1902. Serial No. 128,921.

To all whom it may concern:

Be it known that I, ROBERT M. DIXON, a citizen of the United States, residing at East Orange, county of Essex, State of New Jer- S637; Improvements in Coupler-Hose, of which the following is a specification.

My invention relates to coupler hose and has for its object to produce a structure which will efliciently cou le train pipes. The device, however, is capable of other uses and the invention is not limited to the coupling of train pipes.

In the accompanying drawing, I have shown a device in which my invention is embodied.

In this drawing, Figure I is a side elevation of a construction in which one form of my invention is embodied; and Fig. II is a transverse section through the coupler hose showing its referred construction.

The eading feature of my invention is a flexible hose permanently flexed or bent Jfor the purposes of insuring an efficient coupling action and facilitating coupling and uncoup lin In the drawing, a indicates diagrammatically the ends of the steam train pipe on adjacent cars. Connected to each of these train pi es in any suitable manner as by means o clam s t or other coupling devices is a section of exible coupler hose c. cou ler hose sections are permanently bent or exed as for instance at d and e and each is provided with a disengageable coupler f of the ordinary gravity type. In the present instance, I have shown the `flexible coupler hose of sinuous or ogee form. The coupler hose may be variously constructed. 'In Fig. II, I have shown the same as consisting of a rubber linin r g and rubber jacket 7i with intervening pies or layers of duck i which may be of any re uired number. In the present instance I ave shown six plies or have invented certain new and useful i These layers of duck. The hose is given its permanent l'lexure by the mandrel upon which it is constructed.

Having described my invention what I claim and desire to secure by Letters Patent is:

1. In construction of the class described, in combination, a pair of coupler hose adapted respectively to make connection with train pipes, and a coupler, parts of which are connected with and adapted to join said hose, each of said hose being flexible as a whole and provided with a permanently bent portion curving toward said coupler.

2. In construction of the class described, in combination, a pair of vflexible coupler hose adapted respectively to make connection with train pipes, and a coupler, parts of which are connected with and adapted to join said hose, each of said hose being provided with a permanently bent portion curving toward said coupler and another permanently bent portion curving toward thc corresponding train pipe.

8. In construction of the class described, in combination, a pair of coupler hose adapted respectively to make connection with train pipes, a coupler, parts of which are connected with and adapted to join said hose, each of said hose being` provided with a permanently bent portion curving toward said coupler and another permanently bent portion curving toward the corresponding train pipe, and a ilexible portion intermediate said bent portions.

4. In construction of the class described, in combination, a pair of flexible coupler hose adapted respectively to make connection with train pipes, and a coupler, parts of which are connected with and adapted to join said hose, each of said hose being provided with a permanently bent portion curving toward said coupler.

5. In construction of the class described,

in combination, a pair of flexible coupler hose adapted respectively to make connection with train pipes and hang downwardly thereof which are connected with and adapted to join said hose, each of said vhose being pro- 1 vided with a permanently bent portion curvingtoward said coupler and being flexible as a Whole.

7. In a device 'of Vthe 'class described, a

coupler hose having two oppositely-disposed 21o permanent bends and an intermediate rela tively flexible portion.

R. M, BIXON.'
